In Single Point Operations level 9.2 and earlier releases, Single Point Operations Status provided the capability to define component classes of components and monitor those components at runtime. It was a separate application from SPO Console. Each instance of Single Point Operations Status and each instance of SPO Console loaded a configuration which affected only that instance of the application.

Beginning with level 11.0, Operations Sentinel provides a single application, Operations Sentinel Console, and a single configuration that affects all instances of Operations Sentinel Console. All features of Single Point Operations Status and SPO Console have been merged into Operations Sentinel Console. Operations Sentinel Console was first released in Operations Sentinel level 10.0 and has been extended in later releases to include the features of Single Point Operations Status.

Classifications versus Single Configuration

In Single Point Operations level 9.2, "classifications" contained definitions of "component classes" that defined sets of "components" to be monitored at runtime.

Beginning with level 11.0, Operations Sentinel contains only a single configuration, that is, it does not use classifications. “Component classes” are replaced by "classes" that define sets of "objects."

Like component classes, the user can define classes as part of a configuration definition. Classes have all the features of component classes, including the ability to dynamically instantiate objects and raise alerts based on the state of individual objects.

Attributes versus Properties

In Single Point Operations level 9.2, component classes had "attributes." Attributes define individual pieces of data about an object of that class, for example, the reel id of a tape.

Beginning with Operations Sentinel level 11.0, classes have "properties." Properties function the same as attributes. As the result of enforcing a naming convention, some property names differ slightly from the corresponding attribute names (see Table 1–3, Table 1–6, and Table 1–8).

Table 1–1 summarizes the old and new terminology.
